no, you can complain, even though it is not logically
reasonable, just don't let it become your value system.. becuz you
were upset, so its quite reasonable.
well, people often feel disillisioned about others, not against any
individual or gender or race, but in generality, so its alright,
just that we must work hard not to repeat their mistakes.
quite often, almost everyone will feel unappreciated and taken for
granted.. including me, but there is really nothing much we can do
about it, so no choice but to take it easy, as long we did what we
can do, then its alright le.
i think you can look to know your dad's mistress, mainly to confirm
and see things objectively, if you can manage your emotions
properly. but don't create problems for both your parents by
forcing them to make any hasty decisions.
